Windows 7: Unable to use upgrade key - error code 0xc004f061

Do a clean install with original W7 disk. Activate, go to and select upgrade in programs menu, enter your upgrade code, reboot and done. Worked for me a month ago.

As an afterthought I cleaned with Diskpart first.

I could not do that as the Ultimate version was acquired through Windows Anytime Update. Therefore I do not have media for the upgrade version - only the original prior to the upgrade. And that product key does not work on the new install.

I may just purchase Win 10 and do a clean install with that rather than mess around with multiple installs and then update to Win 10 anyway.

There are NO legal sales of Keys for Windows other than with accompanying software - if you buy from this shop it will almost certainly turn out to be a counterfeit copy. Most such sales will work for a limited period, until the number of activations exceeds the limit, at which time MS will Block the Key from further activations and all current installs will become flagged as non-genuine.
If you've already made a purchase and installed the product I recommend that you visit the Windows 7 Genuine forum and read the Announcements and stickies there - and post an MGADiag report to have the key checked.

Layback Bear, that is what I have found - no legit copies for sale. All are from PC's that have been allegedly "decommissioned". As I want to keep my copy being Genuine, I have no option on this one. Upgarde to Win 10 and pay the price.

Have been taught a lesson about PC repairs though. Do not trust the repair guy. I should have purchased a new disk and installed all myself. An expensive lesson!

I think we are missing a trick here, its only your Ultimate upgrade you are having a problem with - theres nothing to stop you clean installing your original Win 7 version and activating with your original key

If this works ok you can then take the free upgrade route to win 10 currently on offer from MS - the only draw back will be that Ultimate would have upgraded to Win 10 Pro but lower copies of 7 upgrade to Win 10 Home

Windows Updates & Activation

Unable to restore file (error code 0x8100001A)Weeks ago I tried to restart backups after reconfiguring my hard drives. Now backups finish (with some files skipped) but I cannot restore, due to problems validating a zip archive. However, the zip archive mentioned is one that was deleted weeks ago, and it did not exist when the backup was made....

Windows Updates & Activation

Unable to activate "anytime upgrade" - Error Code 0XC004E003All,
First, I will say that I have searched and tried many options to no avail. Here is the history: I bought my laptop with Windows Vista just over 2 years ago (HP G60) with the option to upgrade to Win7 Home. I did a clean install of Win 7 after receiving the disks and replacing the hard...

error code on upgrade installI just got Win 7 Pro Upgrade. My current OS is XP Home SP3. During my install I get either of these error codes: 0xC0000005 and 0x80070570. I have retired 4 times and got either code each time. Upgrade Advisor said I would be fine. Any Idea?
